SERO on SERO

Editor’s note: For this edition of Millipore NOW, we invited Serologicals Corporation to submit a guest article (our first!) - to tell Millipore employees who they are and what their business is all about. So below, in Serologicals’ own words, is a summary of Serologicals today.

After the pending acquisition is completed and Serologicals is part of Millipore, some of the terms and descriptions included here will have changed to reflect the combined strengths of both companies. But this summary will give you a broad overview of Serologicals’ business - right now.

(Thanks to Bill Davis, Serologicals Public Affairs manager, for developing this piece.)
